Ball transmission mechanism is a new type power delivery structure. Based on the merits and demerits analysis of belt, chain, gear and fluid drive, the ball transmission mechanism is put forward. The structure and working process of same or reverse direction ball transmission mechanism were described, and an application example of ball transmission bicycle was given also. There are many characteristics, such as higher transmission accuracy and efficiency, flexible spatial distribution, lower cost, etc. for the new structure, who can replace many traditional transmission mechanism in many application fields.
